I've used Sevin Dust in the past to kill out yellow jackets that build behind vinyl siding. I've tried the new Sevin Dust with main ingredient Bifenthrin and it is pretty much useless against yellow jackets. I've used almost the whole pound, dusting the entrance to the nest every few days and hadn't slowed them down a bit. I ran across an old container of Sevin dust I had bought years ago that contained Carbaryl. Just one day after dusting the entrance with it, yellow jacket activity has almost come to a stop. Within a couple days a expect them to be killed out. The dust is effective in this case because the nest is hidden behind the vinyl siding where sprays can't necessarily reach, but the dust will be tracked into the nest and will eventually kill the yellow jackets. But it is only effective if the insecticide is strong enough to do the job. I'll be looking elsewhere for another product that will do the job and not waste my money.

I use it on ormental flowers. It does NOT affect the insect population. My petunias are being eaten. No moths or caterpillars have been found on the plants this year, however, something is eating on the petunias and the zinnias. I juat wish I could find it and identify it.

Sevin dust works great for insects, including flying insects. When I find ground hornets, usually by being stung while weed eating, I dust the area of their nest. The hornets land in the area, get the dust on their legs and wings and carry it onto the nest killing the entire nest. I've also found it works on hanging nests of you can get it on the nest near the opening.

The dust may be a good product, but I am going to return it because I can not read the label even with a magnifying glass because container is a cylinder.
